' Application filed January 22, 1921.

To all whom it may concern:

Be it known that I, GEORGE W. SMITH, a citizen of the United States, residing at Garber,'inthe county of Garfield and State of Oklahoma, have invented certain new and useful Improvements in Sediment Receiving and Drawing-Off Devices for Tanks, of

which the following is a specification, referencebeing had to the accompanying drawln s.

it is the purpose of the present invention to, provide a sediment or refuse receiving and drawing off device for gasolene and other tanks, constructed to fit within the tank adjacentthe bottom thereof and of conical form, so that the refuse, sediment or 'settlings may deposit thereon, and at intervals, either while the tank is filled, or

when empty the-sediment may be drawn off,

thereby removlng substantially all the foreign matter and leaving a clean supply of gasolene.

Another purpose embodies the provision' of a device of this kind comprising a plurality of triangular frames resting upon the bottom of the tank and connected to a plurality of segments, which constitute the conical container thereby supporting the bottom of the container or sediment receiving device spaced in the bottom of the tank,

so that the clean or clear fluid can be drawn oif from the bottom of the sediment receiving pan' i A still further purpose is the provision of means for fastening the tapered ends'of the sections of the receiving pan together at the apex thereof, and having means whereby a refuseor sediment pipe may be connected to thepan or sediment receiving container, whereby the sediment or refuse can be drawn off at any time, by opening avalve, which is carried by the pipe. 7 l

' While thedesign and construction at present illustrated and set forth isdeemed pref erable, it is obvious that as a result of 'a' reduction of the invention'to a more practical form for commercial purposes, the invention may be susceptible of changes,and the right to these changes is claimed, proare comprehended within the scope of what is claimed.

The invention comprises further features and combination of parts, as will be hereinforth, shown in the drawings and claimed. 1 l

In the drawings Figure l is a view in section of a gasolene tank, showing the improved sediment or refuse receiving container or pan as resting on the bottom thereof, and illustrating the dlscharge pipe for the refuse or sediment.

1g. 2 1s a bottom plan view of the sediment receiving device or container.

1g. 3 is a top plan view.

Fig. 4 is adetail view of one of the radial frames for the bottom of the container or pan.

Referring more especially to the drawings, a gasolene tank constructed of wood, metal or the .like, and which is provided with an intake pipe 2 and drawing ofl plpe 3, there being a conventional form of closure 4 for the tank.-

The improved sediment container or receiving pan 5 is mounted upon the bottom of the tank, and this pan or container comprises a plurality of segments 6. i

' In'order to fasten the segments together, and to insure a rigid construction, a plurality of frames 7 are provided. Each'frame 7 is substantially triangular in contour, and comprises the lower radial bar 8, the relatively wide inclined bar 9, which is braced relatively to the bar 8, with the end uprights 10 and 11. Suitable braces 12 connect the horizontal bar 8 .and the inclined bar 9, thereby reinforcing the frame, and insuring rigidity.

These substantially triangular frames are located adjacent the joints of the segments pan, there being bolts or the like 13 passing through the overlapping parts of the segments and through the bars 9 of the frames, for rigidly connecting the parts. Where the segments join at bars 9 of the frames, the edge'portions of the segments are overlapped. In other words the adjacent edges of' the segments are overlapped, and the bolts pass through the overlapped portions, and also through the bars 9.

' hen the pan or container is made up in this manner consisting of the segments, it is obvious that a duced having a conical form or contour, in other words conically dished, so that the sediment and refuse will eventually pass to the center ofthe pan or container, so that it can be drawn off easily. A conical plate 1 4 is bolted or otherwise secured to the tapered pan or container will be proable gaskets or washers 16- on the extension 'drawingofi'pipe, 1s first rotated in order to bind oneend edge of the elbow aga nst off easily.

ends of the segments, in order to hold the segments relatively rigid, as well as rigid with relation to the frames. This conical plate it 'connects the threaded extension- 15, which passes through the opening'lfi in the bottomlof-thetank so that the extension will extend below thetank, there being suitslightly inclined, so that the sediment or refuse may easily pass out through the p'1pe.- However, before attaching the pipe 18 se-.

f In the use of the device, thetank in which the container or pan 1s located receives the gasolene, the sameenterlng the tank through the pipe 2. After the gasolene or other fluid thoroughly settles in the tank, the; set- I tlings,-refusefor sediment'will finally settle upon the pan or container. It has been found that the sediment or scttlings will eventually find their way to the center of the pan'or-container, where they can be easily drawn off, while the. gasolene will flow un- 1 der the container, and that portion of the gasolene wider-the container is practically clear, and in this case, .by turning onthe valveof the pipe 3, pure clear gasoIenc may be drawn off. After the gasolene settles,the sediment, having been collected in the center drawing off pipe 3 may beopened, allowing the gasolene to pass through the infinite space between the edgeof the falsebottom and the inner circumference of the wall of the tank, leaving the sediment or refuse in the false bottom. In fact a certain amount of sediment may collect at the'edge of the false bottom where it is infinitely spaced from, the inner circumference of the tank,

I and through which thejgasolene will strain,

hence the gasolene which passes throughsaid infinite space will be very clear. vAs the gasolene diminishes, further supply of gasolenevmay be allowed to enter through the pipe 2. In fastening the conical plate 14; tothe innertapered ends of the segments,

it is the aim to alsofasten the plate to the and supporting the false bottom, and a drawing off pipe passing through and connected to thebottom of. the tank andto the'false bottom, whereby-the refuse orsediment may be easily and quickly. removed. 7 2. In' a devicefor the purpose indicated,
